During this particular setup procedure we have made
the voltage setup LED bar more sensitive so that the
adjustment can be made in 0.1V increments. For
example, for 13.1V the 13V LED is on and the 13.4V
LED is flashing. The same idea for 12.9V. The 13V
LED is on and the 12.6V LED is flashing.

The

range you can choose is

Cutoff voltage

between 12.0V-14.6V.

Charging voltage is always 0.2V higher.
Lower voltage trip is always 1.1V lower.
Low voltage trip (Mode 3) is always 3.0V lower.

If you do not touch any buttons for 30 seconds the
default voltage of 13.0V shall be restored and saved.

To confirm your custom voltage you must press
both buttons (SETUP/ENTER) and (SELECT)
simultanously for 2 seconds.

The chosen voltage will be saved and the unit will
restart. If you feel unsure do not touch any buttons.
The default value will be restored automatically.

Modifying input on / off voltage thresholds.

The

default

input voltage thresholds to operate the Pro

Batt Ultra are as follows:

Activation voltage

13.3V-13.6V - the charger turns on

and charges. If the input voltage drops below 13.3V the
charger stop charging instantly. If the input voltage then
goes back to 13.3-13.6V the charger shall charge again.

13.6V+ - the charger turns on and charges. In addition, the
low voltage timer for regenerative braking activates. So,
now, if the input voltage drops to between 12.0V -

Timer

activation V

13.3V the default 120 second timer shall begin

and the charging shall continue for 120 seconds. To then
reset this timer the input voltage has to go above 13.6V+
again. If the input voltage only goes to 13.3V-13.6V the
charger shall start charging but shall not reset the timer. If
12.0V - 13.3V is maintained for longer than 120 seconds
the charger turns off.

12.0V - 13.3V - this is the regen. braking operational
window - only activated when the default 120 second timer
has been activated (input voltage at 13.6V+). Provided the
input voltage remains between 12.0V - 13.3V for over 120
seconds the unit shall stop charging.

Low voltage trip V

<12V - below 12.0V shall result in the

charger turning off immediately - unless in operation mode
3.

11.5V - Low voltage cut off, applicable only when in
operational mode 3. The

CUSTOM INPUT CUTOFF VOLTAGE
SETTING:
(voltages x 2 for 24V)

Here  you  can  adjust  the  input  voltage
setting that prompts the unit into sleep
mode.
This  unit  has  3  different  cut  off  preset
voltages.  In  Auto  Mode  the  cut  off
default is 13.3V and in Regen Braking
Mode the cut off default is 12.0V. The
higher  figure  (Auto  Mode)  and  lower
figure (Regen Braking) are both pegged
together by a 1.3V gap. As these figures
are  pegged,  when  you  change  Auto
Mode you change Regen voltage to be
1.3V lower.
We have designed it, therefore, so you
can only tune the higher voltage (Auto),
this,  then  changes  the  lower  voltage,
respectively (by 1.3V). The 3rd cut off
voltage is only relevant when in mode 3,
the  low  voltage  trip  is  pegged  at  1.8V
lower than the Auto Mode voltage.
For  example,  if  you  want  the  Regen
cutoff  voltage  to  be  11.7V  -  set  the
higher  voltage  to  13.0V  (11.7V+1.3V).
The low voltage trip (if in mode 3) is then
11.2V.

Adjustment of operational voltages.

The 4 main control voltages below are inextricably linked.
The voltages can only be adjusted as a block (not
individually). For example, if you wish to reduce the

Cutoff

voltage

by 0.2V then all other voltages in the block shall

reduce by 0.2V.

regen braking timer

All  4  voltages  are  always
linked.  This  block  can  be
adjusted  by  changing  the

Cutoff voltage

value up and

down. This subsequently
changes the other three
voltages by the same value.

Charging voltage (default 13.2V) (always 0.2V above

Cutoff voltage)

At this voltage the charger starts

charging. After 5 seconds above 13.2V the regen braking
timer is set. If the input voltage drops to 11.9V - 13.0V this
timer begins. Timer reset when input voltage is 13.2V+.

Cutoff voltage (default 13.0V):

This voltage is only

relevant after the

charging voltage

has been met and the

charger is charging. When the input voltage drops below
this cutoff voltage the charger stops charging and shall
eventually go to sleep. If the input voltage remains
between 13.0V-13.2V the charger shall continue charging.
The

Cutoff voltage is the parameter that the user

changes.

change the other three voltages mentioned by the same
amount.

Lower voltage trip (default 11.9V) (always 1.1V below

Cutoff voltage)

When the input voltage drops below the

Lower voltage trip

the charger turns off. The 11.9V

threshold is only relevant if the
